Filed: 1969-10-16
Abstract: 1278991 Arc welding AIRCO Inc 16 Oct 1969 [29 Oct 1968] 50981/69 Heading H2H In an arc welder, the arc voltage is controlled against fluctuations in theline voltage by means of a feedback loop, in which the line voltage is sensed, and compared with a reference voltage. A continuous D.C. voltage is applied to the arc 34, by means of a rectifier 28, superimposed on this is a stabilized pulsed power output derived from terminals 50. The firing angle of thyristors 42 and 44 is controlled by means of pulse shift circuit 60, which is in turn controlled by means of the output of a comparator 62, which compares a reference signal generated in 68 with the line voltage developed across resistors 64 and 66. The feedback loop ensures that the mean value of the voltage developed across resistors 64 and 66 remains constant and does not fluctuate with fluctuations in the power supply. The thyristors 42 and 44 fire thyristors 46 and 48, which control the power supplied to terminals 50. The control thyristors 42 and 44 are in this way isolated from the arc, so they cannot be effected by conditions in the arc circuit.

A D.C. motor 2 is adapted to operate smoothly at a speed lower than that obtaining when it receives a continuous voltage which is just sufficient to overcome static friction. Pulses applied to the motor have an amplitude at least equal to the continuous voltage, and a frequency suitable for starting the motor and maintaining continuous slow running. The motor is supplied from variable transformer 1 through diode 3 and, during the intervals between the unipolar pulses, the back E.M.F. appears across the supply lines 8, 9. The back E.M.F. is separated by filter network 4 and used to charge a capacitor 17 associated with a speed-monitoring circuit comprising ammeter 19.
